GAS AND LIQUID HOLDER.

SPECIFICATION forming part of Letters Patent No. 419,845, dated January21, 18290. Application filed March 28, 1889. Serial No. 304,502. (Nomodel.)

To all whom it may concern:

Be it known that I, JOSEPH FLANNERY, re-

siding at New York, in the county and Stateof New York, have invented acertain new and useful Improvement in Gas and Liquid Holders, of whichthe following is a specification. 7

The object of my improvement is to provide a simple and ready means forstoring liquid, and particularly oil to be used in the manufacture ofgas; to effect a saving of the gaseous vapors arising from theevaporation of the stored oil and prevent the escape of such vapors inthe surrounding atmosphere; to provide means for forcing the liquidstored in the tank, therefore to guard against danger from explosion ofthe oil, and to eifect a saving of ground-space over what has heretoforebeen possible as such storage-tanks have been erected. To accomplishthese results I place a tank for containing the liquid directly withinthe gas-holder, whereby the tank will be always surrounded by water, bywhich the gas-holder is sealed, and will therefore be always kept cooland at the same time so inclosed as to be protected against danger fromsparks or other causes which might tend to induce an explosion. Ifurther provide the tank with a vent by which the gaseous vapors arising from the evaporation of oil within the tank may pass directly into thegas-holder, thereby not only enriching the gas in the holder andpreventing waste, but also providing against the escape of such gaseousvapors into the surrounding atmosphere, as is the common practice, bywhich the atmosphere is contaminated and the health of a neighborhoodendangered. As the tank is in open communication with the gas-holder, inwhich a heavy pressure is maintained, the weight of the holder and thepressure therein will operate to force oil out of the tank through itsdelivery-pipe, and raise it to a considerable elevation when it isdesired to withdraw the oil, the effect being that of a foi-cepump. Thearrangement of the tank within the holder will not curtail the gas-spaceof the gas-holder, for the reason that the space occupied by the tank isordinarily filled with water. By placing the tank within the gas-holderit will be seen also that a considerable savingis effected .cientheight.

in the ground-space over what could be offected if the tank and thegas-holder occupied different and separate positions.

In the accompanying drawings, Figure 1 is an elevation, partly insection, of a gasholder and tank embodying my improvements. Fig. 2 is asimilar view, but partly broken away to save space, and illustrating aslightly-modified construction. Fig. 3 is a plan or top View of theimprovement shown in Fig. 1. Fig. 4 is a vertical section of the tankand shows a slight modification.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the gas-holder, which may be of the usual or any desiredconstruction, adapted to be moved upwardly and clownwardly in the frameB.

O designates the well in which the lower portion of the gas-holder isreceived and in which the water is contained.

a a designate gas inlet and outlet pipes, respectively, which may be ofthe ordinary construction and open directly int-o the gasholder. Theyare provided with cocks s s.

D designates a liquid-tank, which tank has, as shown, a closed bottomand top, and is secured at its lower side to the bottom of the well 0.

d cl are respectively filling and emptying pipes, by which liquid isdelivered. to and from the tank D. They are provided with cocks s 8 edesignates a vent in the upper portion of the tank, by which means opencommunication is afforded between the tank and the gasholder.

In Fig. 4: I have shown that a float f may be employed, which float ismounted upon a spindle f, extending upwardly through the vent e, andupon which is secured a valve f adapted to seat upon a valve-seat fformed upon the inner end of the vent 6 when the liquid in the tankshall have risen to a sufii- This will prevent any overflow of oil intothe water-space between the tank and the sides of the well when oil iscontained in the tank.

In Fig. 1 I have shown the well as made of metal such as plate-iron--andin Fig. 2 I have shown the same as constructed of masonry. In the lattercase the bottom of the well is formed of cement or similar material, andthe tank D rests thereon.

Gaseous vapors arising from oil stored in the tank will pass out throughthe vent e and will become mixed with the gas in the gas holder, therebyenriching such gas and preventing the waste of said gaseous vapors,besides Wholly confining them so that they cannot escape into thesurrounding atmosphere.

- When it is desired to withdraw oil from the tank, the cock 8 in thefilling-pipe cl is closed and the cock 5 in the emptying-pipe d isopened. The weight of the gas-holder and the pressure therein will thenoperate to force oil out through the emptying-pipe and raise it to alevel considerably above the level of the oil in the tank. This isadvantageous where the tank and holder are situated at a level belowthat at which it is desired to use the oil.

Of course instead of using separate pipes for filling and emptying thetank, both operations might be performed through a single pipe.

That I claim as my invention, and desire to secure by Letters Patent, is

The combination, with a gas-holder, of a tank for liquid arranged insaid gas-holder, pipes by which gas is admitted directly into andwithdrawn directly from said gas-holder, a vent in the tank by whichopen communication is afforded between the tank and the gas-holder, anda pipe or pipes communicating with the tank by which liquid may beintroduced into and withdrawn from the tank, substantially as and forthe purpose specified.

JOSEPH FLANNERY.
